There were 37 sets of twins in attendance on the first Twins Days in 1976. Forty years later, it's the largest annual gathering of twins in the world. The festival, held in Twinsburg, Ohio, is open to identical, fraternal, and young and old twins, triplets, quads, and their families. InAlex Markman's film, twins discuss what it’s like to have an identical other half and the joy of being surrounded by thousands of other twins, if only for a few days.

The Short Film Showcase spotlights exceptional short videos created by filmmakers from around the web and selected by National Geographic editors. We look for work that affirms National Geographic's belief in the power of science, exploration, and storytelling to change the world. The filmmakers created the content presented, and the opinions expressed are their own, not those of National Geographic Partners.
